Thanks for the explanation!
What about other males in the family? What are their titles?

They are called 'prince' as well as all the female members are called 'princess' apart from Fürst Alberts future wife who will be 'Fürstin'. Btw, once Albert marries what will Gloria be called? Princess dowager?

Beauty is in the eye of the beholder, but I really think he's losing his looks. He looked quite handsome when younger, but now... I wouldn't call him manly looking either, rather the opposite. To me Elisabeth is the beauty of the family. But then again, it's the character that's by far more important than how a person looks like.

The TV-girl asks: Where are your leather pants ( traditional bavarian clothing that everyones wears at Oktobersfest - it's a must) ?
He says: I'm only here for today and didn't even know some days before that I'd come, because of my busy shedule.

Then she makes comments about his funny hat...
He said, that he has just bought it to look at least a little bit like traditional bavarian men

Then she asks, if he'll come again this year with his family....
He said: it's not possible/ too busy

Then she said: We, Albert and I, had to take some funny positions for this interview. I'm so small and Albert is so tall, that he had to come down and to sit on a little wall-something. Otherwise the camera couldn't have taken picture of us together.

Then his friend, sitting on a bank said, Albert just did that to look at the reporters decollete. He laughs....and says good bye.

Officially she is already ( since 1990 ) : HSH The Princess Dowager and her daughter-in-law will be called HSH The Princess of Thurn and Taxis

In German: "Fürstin Gloria von Thurn und Taxis" and her daughter in law will be called " Die Fürstin von Thurn und Taxis".

But in short form it will be: Fürstin / Princess Gloria and Fürstin/ Princess XYZ

Please notice that there is no and won't be any "Fürstin" in Germany. Gloria is legally Gloria Prinzessin von Thurn und Taxis. Her daughter-in-law could take the last name "Prinzessin von Thrun und Taxis". But she also could not be "Fürstin".
In Germany, the constitution of the Weimar Republic in 1919 abolished nobility and all nobility titles. They are now merely part of the family name, and there is no more right to the traditional forms of address (e.g., "Hoheit" or "Durchlaucht"). Although the German Federal government does not recognize "noble" or "royal" status per se, members of the former royal, princely, and noble houses of German descent use their "titles" which the German government regards as last names. There is no existing monarchical class system in Germany.
So e.g. "Albert Prinz von Thurn und Taxis" did legally not become "Fürst", when his father died, because last names stay even when your father died.

Yes, we are aware of this but we aren't concerned with German Federal government recognition, or lack thereof.
As this is 'The Royal Forums' we may continue to use the royal and princely designations, just as I note that some of the German media do.
So, HSH (Durchlaucht) Fürst Albert it is.
